Consider a sealed cylindrical container released from a height h = 3.0 m and rolling without friction on an inclined plane. How much water should be added to the container so that its final speed, reached at the end of the inclined, increases by 15%? Consider that water slides without friction inside the container, m_container = 4.0 kg, g = 9.80 m/s², and in both cases the cylinder is released from the same height.
